How do you recomend I recalibrate my orp probe. It is giving me crazy high readings with no ozone. It is about 1.5 years old and been cleaned. What orp calibration fluid should I use, or since it is so expensive do I get a new probe.
Use the procedure described in the manual. You need quinhydrone, pH 4.0, and pH 7.0 calibration solution. Also shut off pH compensation as that will result in higher ORP reading.
